SOURCE: O2 sensor and EVAP issues
P0446 is Aux Emission Control
P0132 Fuel Air Metering
The Evap Canister is located in the fender well, if I am not mistaken and the B1S2 is the O2 sensor is the second O2 sensor on the left side of the engine if your looking at it from the front of the motor.

SOURCE: i have error codes p0156 p0161
Check the wire harness near the top of the engine in the rear. They were good for rubbing through on the trans fill tube bracket. Judging by the code you have 4 sensors. you would be interested in the drivers side rear sensor.

this is very common on these. the upper intake seals leak and should be replaced. It is not a noticable vacuum leak and is usually worse when the engine is cold. It is not a very difficult job to do

Those codes are for the oxygen sensors, lean fuel mixture on both banks. Change them, problem with stalling and rough idle should go away.

System Too Lean (Bank 2)
Basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exhaust.
Note: This DTC is very similar to P0171, and in fact your vehicle may show both codes at the same time.
